Package: fail2ban Version: 0.8.13-1 Severity: important Dear Maintainer,
When trying to use fail2ban with the default config (only the ssh jail enabled), it does not seem to be able to ban IPs because of iptables errors: 2017-04-21 15:06:08,768 fail2ban.jail [26836]: INFO Creating new jail 'ssh' 2017-04-21 15:06:08,772 fail2ban.jail [26836]: INFO Jail 'ssh' uses poller 2017-04-21 15:06:08,926 fail2ban.jail [26836]: INFO Initiated 'polling' backend 2017-04-21 15:06:08,935 fail2ban.filter [26836]: INFO Added logfile = /var/log/auth.log 2017-04-21 15:06:08,940 fail2ban.filter [26836]: INFO Set maxRetry = 6 2017-04-21 15:06:08,951 fail2ban.filter [26836]: INFO Set findtime = 600 2017-04-21 15:06:08,956 fail2ban.actions[26836]: INFO Set banTime = 600 2017-04-21 15:06:09,343 fail2ban.jail [26836]: INFO Jail 'ssh' started 2017-04-21 15:06:09,439 fail2ban.actions.action[26836]: ERROR iptables -N fail2ban-ssh iptables -A fail2ban-ssh -j RETURN iptables -I INPUT -p tcp -m multiport --dports ssh -j fail2ban-ssh returned 100 If I run the commands mannually, I get this: pierre@BMO ~> sudo iptables -N fail2ban-ssh iptables: Chain already exists. pierre@BMO ~> sudo iptables -A fail2ban-ssh -j RETURN pierre@BMO ~> sudo iptables -I INPUT -p tcp -m multiport --dports ssh -j fail2ban-ssh iptables: No chain/target/match by that name.
